Forecasting subcritical cylinder wakes with Fourier Neural Operators

Kavli Affiliate: Morteza Gharib | First 5 Authors: Peter I Renn, Cong Wang, Sahin Lale, Zongyi Li, Anima Anandkumar | Summary: We apply Fourier neural operators (FNOs), a state-of-the-art operator learning technique, to forecast the temporal evolution of experimentally measured velocity fields. FNOs are a recently developed machine learning method capable of approximating solution operators […]

Three-dimensional integration enables ultra-low-noise, isolator-free Si photonics

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Chao Xiang, Warren Jin, Osama Terra, Bozhang Dong, Heming Wang | Summary: While photonic integrated circuits (PICs) are being widely used in applications such as telecommunications and datacenter interconnects, PICs capable of replacing bulk optics and fibers in high-precision, highly-coherent applications will require ultra-low-noise laser sources […]

Quadratic-soliton-enhanced mid-IR molecular sensing

Kavli Affiliate: Alireza Marandi | First 5 Authors: Robert M. Gray, Mingchen Liu, Selina Zhou, Arkadev Roy, Luis Ledezma | Summary: Optical solitons have long been of interest both from a fundamental perspective and because of their application potential. Both cubic (Kerr) and quadratic nonlinearities can lead to soliton formation, but quadratic solitons can practically […]

Phase transitions of wave packet dynamics in disordered non-Hermitian systems

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Viktor Könye, Fabian A. Gerritsma, Ion Cosma Fulga, Anton R. Akhmerov | Summary: Disorder can localize the eigenstates of one-dimensional non-Hermitian systems, leading to an Anderson transition with a critical exponent of 1. We show that, due to the lack of energy conservation, the […]
